Question:

If the margins of sepals or petals overlap one another but not in particular direction, the aestivation is called

Options:

1. Imbricate
2. Valvate
3. Open
4. Twisted

Solution:

When the margins of sepals or petals overlap one another, but not in a particular direction, the aestivation is called imbricate. In imbricate aestivation, the sepals or petals overlap each other with one margin external (outer) and the other margin internal (inner) to its adjacent sepals or petals. This arrangement gives the appearance of tiles on a roof, with the margins overlapping in a shingled pattern. Imbricate aestivation is commonly found in flowers of many plant species and is an important characteristic used in plant taxonomy and identification.
